3216 2RS1 – SKF, Double row angular contact ball bearing with seals or shields, 80x140x44.4

3216 2RS1 – SKF, Double row angular contact ball bearing with seals or shields, 80x140x44.4 Double row angular contact ball bearings, with seals or shields, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. Depending on the sealing execution, they can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions. High-speed capability Accommodate relatively high radial loads, high axial loads in both directions and tilting moments Suitable where a stiff bearing arrangement is required Require less axial space than equivalent pair of single row angular contact ball bearings Integral sealing prolongs bearing service life Dimensions Bore diameter 80 mm Outside diameter 140 mm Width 44.4 mm Contact angle 30 ° Performance Basic dynamic load rating 106 kN Basic static load rating 95 kN Reference speed 5 000 r/min Limiting speed 4 300 r/min Properties Contact type Normal contact (two-point contact) Number of rows 2 Locating feature, bearing outer ring None Ring type One-piece inner and outer rings Cage Sheet metal Arrangement of contact angle (double-row bearing) Back-to-back (O) Matched arrangement No Universal matching bearing No Axial internal clearance CN Material, bearing Bearing steel Coating Without Sealing Shield on both sides Sealing type Non-contact Lubricant None Relubrication feature Without
